Molecular Ecology Resources, Volume 26, Issue 3, April 2026.ABSTRACT Environmental DNA (eDNA) metabarcoding can rapidly characterise biodiversity, yet its accuracy and effectiveness are limited by incomplete DNA barcode reference databases. We evaluated how comprehensive reference databases that include sequence variation within genomes (intragenomic) and across individuals and species (intergenomic) improve ...

Advanced Science, Volume 13, Issue 16, 18 March 2026.Radiotherapy induces tumor cells to release microparticles (RT‐MPs) into the circulation. The mitochondrial DNA carried by these RT‐MPs activates the STING/NLRP3/GSDMD axis in splenic neutrophils, triggering IL‐1β secretion. This, in turn, enhances dendritic cell function and facilitates the formation of cytotoxic T lymphocytes, thereby promoting ...

Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes
Advanced Science, Volume 13, Issue 13, 3 March 2026.Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.
